order that it may be fully understood refer.- ence. is to be had to the accompanying drawings, in which Figure 1, is a side view of a switch-stand of a part of the hand lever whereby the switch 15 operated; Flg. '11s a horizontal section onthe line VII of Fig. 1 and showing the method of connectlng the. signal in 2 which extends suhstantiallv arallel p 7 which lever 3 operates. v

Lever 15 is provided with an offset lug or heel 17, through which. it is pivotally connected .by a link 18 with a pull lever 19 5 ing pin 13. from the path of lever 3, and which returns by gravity to its ori-; ginal position when the foot standard with the main standard of the locking pin, it being noted that when the at switch-stand. Fig. 8, is an enlarged section ,tendant operates the foot lever. the lever 15 on line VIII. of Fig. 3. Fig. 9. is a section swings in the direction indicated by the arrow on line IX--IX of Fig. 8L V F ig'. 2, and that such movement of said lever In the said drawings, 1 is a standard, and is retersed'when the attendant relaxessuch g carried thereby there is a horizontal pivot foot pressureto permit the weight-21 a; ref

turn the locking pin to operative position;

pressure remo.ved .,to effect the readvancement of said g roeaeao The lever 15 is provided with an extension or handle 22 so that it may be operated by hand, if desired, and also to make it more convenient for applying -a mechanism for locking the locking pin in its advanced or operative position. As shown the standard is provided near its upper end with a suitable lock indicated only by thekey-hole 23 and a bolt 24 projecting from the handle 22.

look when the lever swings to operative position, it is desirable to provide guiding means as a precaution against play of the lever, due to wear at its pivotal point, and

25 the guiding means shown consists of a pair of pins 26 and 27 projecting from the standard and flaring at their outer ends' to facilitate the entrance of the lever between them. The outer end of one of the pins preferably is in the form of an eye, as shown most clearly in Fig. 3, so that when the lever is in operative position, an eye 28 rigid therewith, will register with the eye of the said pin'and thus permit the lever to be looked in 5 operative position by means of a padlock, not shown, in the event that the automatic locking mechanism identified by characters 23 and 24, is out of commission.

This switch stand isequipped with the usual day and night signals 29 and 30, the former being the usual colored disk, and the latter a lamp. In the ordinary signals the lamp turns whenever the switch stand is operated, and it frequently happens that the operation of the stand results in the extinguishment of the light. To guard against this result l provide the following construction: 31 is a shelf projecting diagonally from the standard toward the trackway, and 32 is a standard provided with a foot fitting upon and bolted as at 33 to said shelf, and in this connection it is desired to state that the shelf and standard 32 are of separable construction for convenience of the repair of the switch stand, as otherwise part 32 is for all intents and purposes rigid with the standard 1. Standard 32 terminates at its upper end in a vertical cylindrical stub shaft 34 upon which is journaled a disk 35, provided at diametrically opposite sides with a pair of short projecting arms 36. It

is also provided at diametrically opposite sides and at right angles to the plane of the arms 36, with a pair of outwardly projecting arms 37 and 38, the latter carrying an upright staff 39, for the direct support of the. day signal 29. Above the disk 35 the stub shaft 34: terminates in a reduced angular portion 40, upon which nonrotatably fits a disk 41, forming the support of an ordinary switch stand lamp 42, and inclosing said lamp is the customary four-lens casing l3 forming in conjunction'with the lamp, the night signal 30, hereinbefore referred to, and in order that the lamp casing 43 shall be turned each time the switch is thrown, said casing fits at its lower end around the disk 35 and is interlocked therewith. The preferred method of interlocking the casing is to provide its lower end with notches 1 i adapted to receive the projecting arms 36, 37 and 38 of the-said disk 35 as shown most clearly in Figure 5, this construction being desirable in order that the lamp proper may be readily accessible when it is necessary to provide it with a new charge of oil or to trim or replace the wick.

I do not claim herein the particular construction of the signal above described.

To impart a quarter revolution to the lamp casing and the day signal, with each operation of the switch, a link l5 is pivot-- ally connected at its ends to a pin 46 carried by arm 37 of disk 35, and to a pin 47 pivoted to the upper end of lever 7.

4:8 is a bar pivotally connecting the lower end of lever 3 with the switch, not shown.

This bar for the purpose of guarding against injury to the switch points, is preferably constructed as follows: 49 is a tubular member directly pivoted to the lower end of lever 3. 50 is a member directly connected at one end in the usual or any preferred manner to the switch and fitting telescopically at its opposite end in member 49 and provided with a longitudinal slot 51. 52 is a flanged sleeve fitting slidingly on member 50 and connected by tie bolts 53 to the flange 54c of member 49. 55 is a collar fitting slidingly on member 50. sleeve fitting at one end on sleeve 52 and at its opposite end secured. by a pin 57 to collar 55, which pin extends through the slot 51 of member 50. 58 is an expansion coiled spring fitting around member 50 within sleeve 56 and bearing at its opposite ends against sleeve 52 and collar and normally holding the latter against the outer end of member 4:9, and 59 is a pin rigid with member 50 and normally bearing against-the outer end of sleeve 52. Under ordinary conditions, that is when not being oscillated, the extension 10 of lever 7 occupies the position shown in full lines Fig. 1, to avoid hiding or partially hiding the lens of the lamp, facing toward a train approaching the switch-stand from the side thereof occupied by said lever. I

To operate the stand, the switchman, first swings the extension. 10 of said lever 7 to case the switch ation explained, the casing of the night sig-' nal and the day signal, are turned a quarter revolution in the direction indicated by the adjacent arrows on Figs. 3 and 5 and the bar 48 moved in the direction of the arrow in Fig- 8, it being obvious that the pull on member 49 of said bar 48, is imposed on member 50 through the instrumentalit y of sleeve 52, spring 58-, collar and pin 57,

the spring being sufliciently strong to accomplish this 0 eration without perceptible contraction. en the operation of the switch stand is reversed, the signals are restored to their original positions and the switch is likewise restored to its original positiomand in the restoration of the switch the push on member 49 is transmitted to member 50, through the collar 55, spring 58, sleeve 52 and pin 59. It will thus be seen that when the switch is operated from thesgand, the spring 58 is inoperative, the func't%n' of said spring being to yield to' prevent inj=ury to the switch points in the event lateral pressurelis applied thereon by a passing train when the switch stand is locked, as in this point under ordinary conditiohs would be injured if: provision was not made to permit member 50 to yield without corresponding movement on the part of the lo'c'lted member 49. Assuming that the switch points do move under such circumstances and therefore move member 50 in the direction indicated by the arrow hereinbefore referred to, the movement of said member 50 is transmitted through pin 59, sleeve 52 and the spring 58 yields to such move ment of the sleeve. Should the switch be moved in the reverse direction, it imparts movement through-the pin 57 to collar 55 and sleeve 56, the spring yielding to accommodate this movement because the tie rods 53 prevents corresponding movement on the part of sleeve 52. It will thus be seen that provision is made to guard against injury to the switch points in the event movement is imparted to the same in either direction when the switch stand is locked. The pin 2 on which lever 3 is fulcrumed, while sufliciently strong to resist the strain incident to the opening and closing of the switch, is preferably adapted under the imposition of extraordinary strain, such for instance as might occur when the switch stand is locked and the switch is moved by a passing train in opposition to the locking pin, to

break, as the breaking of such pin is preferable to injury tQ any other part of the embodying the lock .the lever in the switch stand, because such pin can be easily and cheaply replaced. I

From the abovedescription it will be apparent that I have produceda switch stand features of advantage enuinerated as desirablegand which obviously is'susceptible of modification in'minor partlculars without departing from the spirit and scope of the invention as defined by the appended claims.
